Deep Inelastic Scattering on Ultracold Gases

Physical Review X, 2017
We discuss Bragg scattering on both Bose and Fermi gases with strong short-range interactions in the deep inelastic regime of large wave vector transfer q, where the dynamic structure factor is dominated by a resonance near the free-particle energy ℏω=ϵ_{

Soft corrections to inclusive deep-inelastic scattering at four loops and beyond

Journal of High Energy Physics, 2020
We study the threshold corrections for inclusive deep-inelastic scattering (DIS) and their all-order resummation. Using recent results for the QCD form factor, related anomalous dimensions and Mellin moments of DIS structure functions at four loops we ...

Rise of the DIS structure function F L at small x caused by double-logarithmic corrections

Journal of High Energy Physics, 2021
We present calculation of F L in the double-logarithmic approximation (DLA) and demonstrate that the synergic effect of the factor 1/x from the α s 2 $$ {\alpha}_s^2 $$ -order and the steep x-dependence of the totally resummed double logarithmic ...

Shadowing in neutrino deep inelastic scattering and the determination of the strange quark distribution [PDF]

, 1998
We discuss shadowing corrections to the structure function $F_2$ in neutrino deep-inelastic scattering on heavy nuclear targets. In particular, we examine the role played by shadowing in the comparison of the structure functions $F_2$ measured in ...

Lorentz and CPT violation in partons

Journal of High Energy Physics, 2020
A framework is presented for the factorization of high-energy hadronic processes in the presence of Lorentz and CPT violation. The comprehensive effective field theory describing Lorentz and CPT violation, the Standard-Model Extension, is used to ...

A new approach to semi-inclusive deep-inelastic scattering with QED and QCD factorization

Journal of High Energy Physics, 2021
We present the details of a new factorized approach to semi-inclusive deep-inelastic scattering which treats QED and QCD radiation on equal footing, and provides a systematically improvable approximation to the extraction of transverse momentum dependent

Photon–jet correlations in deep-inelastic scattering

European Physical Journal C: Particles and Fields, 2017
The reaction $$e + p \rightarrow \gamma + \mathrm{jet} + X$$ e + p → γ + jet + X is studied in QCD at the next-to-leading order. Previous studies on inclusive distributions showed good agreement with ZEUS data.

Twist-2 relation and sum rule for tensor-polarized parton distribution functions of spin-1 hadrons

Journal of High Energy Physics, 2021
Sum rules for structure functions and their twist-2 relations have important roles in constraining their magnitudes and x dependencies and in studying higher-twist effects. The Wandzura-Wilczek (WW) relation and the Burkhardt-Cottingham (BC) sum rule are

Novel corrections to the momentum sum rule for nuclear structure functions

Physics Letters B, 2022
We address novel features of deep inelastic lepton scattering on nuclei at small Bjorken variable xBj. In this regime the lepton-nuclear cross section involves the interference between the standard lepton-quark scattering amplitude for the deep inelastic

Transverse Momentum in Semi-Inclusive Polarized Deep Inelastic Scattering and the Spin-Flavor Structure of the Proton [PDF]

, 2002
The non-valence spin-flavor structure of the nucleon extracted from semi-inclusive measurements of polarized deep inelastic scattering depends strongly on the transverse momentum of the detected hadrons which are used to determine the individual ...
